Test date dilemma

Chadertron

Hi all, Looking for general advice. I am applying to multiple Canadian law schools for the 2020 year and had originally planned to take the January 2020 test thinking it would give me the most time to prepare and that the disadvantage in the application process would be worth it. Currently, I am doubting myself and have set up to write the test in November. However, I am doing applications and haven't had a huge opportunity to do full tests yet as I am still finishing the curriculum (just starting Reading Comp) and I feel I will just do the November test and will do awful. On my first test I took I got a 150 and I am hoping to score above a 165 with the knowledge from the curriculum and with at least 10-20 tests completed from now to November. so I guess I have two main questions - What is the cost of writing in January as opposed to November and do you think I am being reasonable? Thanks for any help!
